      The issue is connected to a defect in Fluent 2019R1 where a null residual condition was registerd as unconverged. The solver would keep checking the convergence of that residual even afterl other convergence criteria are met. As a workaround set 1 ( or any large number) for the residual absolute criteria so that residual convergence is correctly verified and always occurs before the convergence of other monitored quantities.
